Hi everyone,

 

I know that there have been a lot of 4870-related questions but unfortunately I'm still having trouble and I'm hoping that somebody can steer me in the right direction.

 

I'm running 10.6.2, using Chameleon RC4. My 4870 is 512 MB, made by Asus.

 

What I've tried so far:

 

1. EVOenabler.kext: This works, but the display doesn't wake from system sleep. Also, performance isn't as good as I would expect (it doesn't seem to be any better than the 9600GT I replaced). I haven't done any specific performance testing though.

 

2. No kext, but this lot in DSDT.aml: Appears to do the same as EVOenabler, ie. sleep doesn't work properly.

 

3. I've dumped my card's ROM into /Extra/ati_9440_1002.rom and added GraphicsEnabler=Yes to Chameleon (and removed the DSDT changes). This results in a garbled screen once the desktop would normally appear.

 

I'm currently running with option 2, but it would be very good to get sleep working properly (especially since I'm clicking it out of habit and needing to hard reset all the time!)

 

Does anyone have any pointers or solutions?

 

Thanks :)

 

 

Update: I've switched to option 1, as I had WoW crash twice within 30 minutes with option 2 (no crashes with option 1 yet).

Unfortunately I'm still stuck. I've replaced Chameleon with PC EFI 10.6 as I've seen a few PC EFI success stories, but I've had no luck yet.

 

EVOenabler continues to not wake from sleep properly. GraphicsEnabler=Yes still produces a garbled screen. Is anyone able to provide any advice or pointers at all? Even if you're not certain, please give me things to try.

 

Thanks :blink:

I've tried Chameleon RC4, and PC EFI 10.6 w/ GraphicsEnabler set to yes. no other modifications

 

I get my primary monitor working fine... but it's 'mirrored' on my second display. 2nd display isn't detected in system profile or in display options.

 

help?

Unfortunately that doesn't work for my system. I can't boot at all without DSDT (I get an HPET-related kernel panic), and if I try GraphicsEnabler with no ROM then I can't see anything on the screen (the system appears to be working apart from that though).

 

Oh well, maybe somebody else will have some suggestions.

 

I don't have a second display handy at the moment so I can't say whether spanning works under EVOenabler.

Hmm. I've just rebuilt the DSDT from scratch (using ACPIPatcher) without adding any graphics-related code and it's still doing exactly the same thing in all cases (EVOenabler, GraphicsEnabler with ROM, and GraphicsEnabler without ROM). I thought that there might still be some nVidia code in there from back when I had my 9600 GT, but that's obviously not it.

 

I haven't mentioned my motherboard yet: Gigabyte GA-EP45-DS3.

It's been a while since my last post but I have everything working now :D

 

I'm using option 3 from my first post, with the display connected using DVI and a DVI-to-VGA dongle in the second port. I'm running 10.6.3 now (and couldn't get anything to work with 10.6.2). Sleep works now!

Hi MacManX,

 

May I know what monitor you use ?

Currently Iam using Sapphire hd4870 512mb and I have exact problem like yours... Monitor sleep works like a charm, but the deep sleep cannot power up the monitor back.

 

Can you tell me the step by step to make the rom and attach it to plist ?

 

Thanks.
